Yes, it has vacuum operated flaps/valves. Supposedly the vacuum is controlled to some extent by the computer but it sounds like it is open all the time, except perhaps at idle. One of the vacuum dash pots has a torn diaphram and Sunset Porsche is helping me find the correct replacement. I would just wire these bypass flaps closed but my wife likes to be obnoxious.
